on October 29, 1953 Chrysler changed the way to jack race cars, AND made pit stops faster.... with a warehouse pallet jack!

used a method of hoisting the car for tire changes even faster than the “rocker jacks” used at the Indianapolis 500. 

This was a hydraulic lifter of the type used to move freight in warehouses.
